ABSTRACT
Objective:
To investigate the risk factors of infarct growth rate of elderly acute ischemic stroke(AIS)patients with endovascular treatment(EVT)and its influence on prognosis.Methods:
Elderly AIS patients who underwent EVT at Beijing hospital from June 2016 to October 2020 were retrospectively included.Infarct growth rate(ml/h)=infarct core volume(ml)/time from stroke onset to CTP examination(h).Based on the rate of infarct growth and the patient's clinical severity, ROC curve was established, and the cut-off value of the ROC curve was obtained.By the cut-off value of the rate of infarct growth, the patients were divided into cerebral infarct slow-growth group and rapid-growth group.Predictors of rapid growth in infarct were analyzed by univariate and multivariate analysis.The patients were divided into good prognosis group(mRS score 0-2)and poor prognosis group(mRS score 3-6)according to the mRS score at the day 90 and the predictors of poor prognosis were analyzed separately.Results:
A total of 67 elderly AIS patients were included with age ranging from 65-96 years and an average of(78.8±7.6)years.(1)The cut-off value of the optimal infarct growth rate for patients with good and poor prognosis was 8.89 ml/h.The patients were divided into fast-growth group(26 patients)and slow-growth group(41 patients)according the cut-off value.(2)Multivariate logistic regression showed that only poor collateral circulation was an independent predictor for fast infarct growth( OR=0.162, 95% CI 0.053-0.489).(3)Faster infarct growth rate( OR=1.173, 95% CI 1.044-1.318)and high NIHSS score( OR=1.146, 95% CI 1.018-1.291)were predictors of poor prognosis.Conclusions:
Collateral circulation status is a major influencing factor for the infarct growth rate, and a faster infarct growth rate is a predictor of poor prognosis for elderly AIS patients after endovascular treatment.
